A door assembly for an animal enclosure includes a door frame and a door each having a plurality of interconnected horizontal and vertical wires. The door frame defines an opening for an animal to pass therethrough, and the door is slidably coupled to the door frame such that it moves between an open position and a closed position relative to the door frame to allow egress and ingress through the opening. A catch member is coupled to the door frame. A latch includes a base member, a bolt, and a lever portion. A first vertical wire and a second vertical wire of the door are spaced from one another such that the first vertical wire is at a first end of the door and the second vertical wire is at a second end of the door. In the closed position, the bolt is coupled to the first vertical wire.

A hamster house, which relates to the technical field of breeding devices, comprises: a box body and a movable door. An active cavity is provided inside the box body, an opening communicating with the active cavity is provided on the box body, and the box body is detachably assembled by several flat plates. The movable door is hinged and used to cover the opening. The box body includes: a bottom plate, side plates, a first panel and a second panel. Two side plates are provided and riveted on two ends of the bottom plate, and the two side plates are oriented to the same direction. The first panel is arranged between the two side plates, and the first panel is oriented to the same direction as the side plates.

A fragile substance storage transportation and release device comprises a frame for inserting cartridges to hold the fragile substance; a propulsion unit for propelling the fragile substance out of successive cartridges, cartridge by cartridge; and an opening mechanism for opening each cartridge one by one in coordination with a propulsion mechanism. The device is useful for distribution of fragile insects such as mosquitoes and there is a mechanism for automatic collection of insects from pupae.

A cage for housing laboratory animals, said cage comprising a tray and a cover which can be removed and switched between a first closing position, in which it is positioned on said tray thus stopping the access to the internal space delimited by said tray, and a second opening position, in which said internal space may be accessed.

A lock (21) for an animal cage (11), the lock (21) being configured for locking a first wire mesh panel (13) of the cage to an adjacent second wire mesh panel (14), the lock comprising: a fastener (29, 31) for coupling the lock (21) to said first panel (13) in the vicinity of a peripheral edge of said first panel; a panel support (36) for supporting a peripheral edge portion of said adjacent second wire mesh panel (14), and a two-part locking mechanism (39, 41) reconfigurable between a first position in which said peripheral edge portion of said adjacent second wire mesh (14) panel is retained in said panel support (36) and a second position where said peripheral edge portion of said adjacent second wire mesh panel (14) can be moved out of said support (36).

An animal house includes an impermeable hollow-moulded structure having at least one convex surface. The structure includes a first flat surface extending in a first direction and a second flat surface extending in a second direction. The convex surface connects the first flat surface to the second flat surface. The structure further includes a rib defining a sharp edge. The rib is configured to be releasably attached proximate to or on the convex surface such that the rib diverts a liquid flowing over the convex surface away from the structure. An impermeable hollow-moulded panel with protruding ridges is also provided to prevent water ingress.
